Hi there!
<em><u>FACTS</u></em><em> :</em>
<em>4.5% is equal to → 4.5/100, which is equal to → 4.5 ÷ 100 = 0.045</em>
<em>Also, the word "of" in "4.5% of $30,940" is the same thing as a multiplication sign. </em>
<u>STEPS TO ANSWER:</u>
4.5% of $30,940 = 0.045 of $30,940
0.045 of $30,940 = 0.045 × $30,940
0.045 × 30,940 = 1,392.3
$1,392.30 = Jack's amount witheld yearly for state tax income. → ANSWER
There you go! I really hope this helped, if there's anything just let me know! :)
The answer would be yes. The way to solve this is by simplifying the first ratio. The first ratio should be girls to boys, which is 6:9. And since ratio can be fractions, 6:9 could be 6/9. Since 6/9 can simplify, you would get 2/3. Now we need to add the 2 girls and 3 boys back into the ratio. The ratio would then look like 8:12. And 8:12 could be 8/12, and 8/12 can be simplify, we get 2/3. So this means that the ratio stayed the same.
45 miles / 1 hour = 45 miles / 60 minutes
Set up a ratio:
45mi/60m = x mi/1m
x = (45×1)÷60 = 0.083333.... mi
Approximately 0.083 miles per minute
now, if we a "prime factoring" of each number, we get
204 =
2*2*3*17
120 = 2*
2*2*3*5
168 = 2*
2*2*3*7
now, notice the GCD for all three is that common bolded values, namely 2*2*3, or 12, so each room will house 12 participants,
now, how many rooms for all German? 204 ÷ 12, or 17 rooms.
how many rooms for all English ones? 120 ÷ 12, or 10 rooms.
how many rooms for the French ones? 168 ÷ 12, or 14 rooms.
so the total amount of rooms for all of them is
17 + 10 + 14.
